IL‐17‐producing γδ T cells

Abstract
IL-17 is produced not only by CD4+ αβ T cells, but also CD8+ αβ T cells, NKT cells, and γδ T cells, plus some non-T cells, including macrophages and neutrophils. The ability of IL-17 to deploy neutrophils to sites of inflammation imparts this cytokine with a key role in diseases of several types. Surprisingly, γδ T cells are responsible for much of the IL-17 produced in several disease models, particularly early on.
